Abstract

Renewable Energy Communities (RECs) offer a decentralized approach to integrate Distributed Energy Resources (DER) and non-programmable Renewable Energy Sources (RESs), such as photovoltaics (PVs). However, achieving full self-sufficiency and maximizing the use of RESs remains a challenge due to seasonal variability and differences between supply and demand. This study explores energy flexibility in RECs using centralized Demand Response (DR) strategies adapted to the Italian context. A single prosumer with PV generation and multiple consumers with varying building characteristics are considered. Centralized linear programming (LP) is used to optimize energy management and coordinate the collective consumption of prosumer-generated PV. The results show that coordinated building response increases PV self-consumption and reduces electricity costs, but the potential for flexibility depends on factors such as community composition, PV availability, and energy sharing strategies. For example, aggregate displaceable energy for pre-cooling drops from 56.39% (one consumer) to 23.33% (six consumers), while larger PV systems improve flexibility (e.g., from 23.33% with 5.4 kWp to 50.56% with 10.8 kWp of energy shifted for pre-cooling strategies). In addition, DR strategies aligned with prosumer self-consumption demands can allow up to 51.96% of displaceable energy for pre-cooling and 30.91% for pre-heating. Thus, tailored strategies in REC design and operation are essential to maximize energy and economic performance, emphasizing the importance of customized solutions for sustainable and resilient energy systems.

可再生能源社区的需求响应：探索意大利框架中产消光伏发电和灵活总需求的协调

可再生能源社区（RECs）提供了一种分散的方法来整合分布式能源（DER）和不可编程的可再生能源（RESs），如光伏（pv）。然而，由于季节变化和供需之间的差异，实现完全自给自足和最大限度地利用RESs仍然是一项挑战。本研究利用适应意大利国情的集中式需求响应（DR）策略探讨了RECs的能源灵活性。考虑具有光伏发电的单个产消者和具有不同建筑特征的多个消费者。集中式线性规划（LP）用于优化能源管理和协调产消光伏的集体消费。结果表明，协调的建筑响应增加了光伏自用并降低了电力成本，但灵活性的潜力取决于社区组成、光伏可用性和能源共享策略等因素。例如，用于预冷的总可替代能量从56.39%（1个用户）下降到23.33%（6个用户），而更大的光伏系统提高了灵活性（例如，从23.33% （5.4 kWp）到50.56% （10.8 kWp）的预冷策略转移能量）。此外，与产消者自我消费需求相一致的DR策略可以允许高达51.96%的可替代能源用于预冷，30.91%用于预热。因此，REC设计和运营中的量身定制策略对于最大限度地提高能源和经济效益至关重要，强调了定制解决方案对可持续和弹性能源系统的重要性。
